Problems solved by technology

[0003] Polypropylene fiber itself lacks polar and functional groups, and it is difficult to dye. Neither dope dyeing nor polypropylene modified dyeing is suitable for the application of polypropylene in the clothing industry. Therefore, research and development of dyes and dyeing methods suitable for polypropylene fiber dyeing have become an important subject

Embodiment 1

[0024] (1) Weigh 0.25g of Disperse Blue, Disperse Red and Disperse Yellow, add 7.5g of self-crosslinking adhesive, add water to make up the total mass to 50g, stir at 37°C for 10min at a speed of 500 rpm, and make a disperse dye color paste;

[0025] (2) Add 0.5 g of printing thickener to the disperse dye color paste, and stir at a high speed to prepare a disperse dye printing paste.

[0026] (3) Spread the polypropylene non-woven fabric on the rubber pad and put the printing screen frame. Pour the adjusted disperse dye printing paste into the printing screen, along the direction of scraping, tilt the rubber scraper, scrape back and forth twice evenly, and then lift the printing screen frame.

[0027] (4) Take out the printed polypropylene non-woven fabric and dry it in an oven at 90°C for 5 minutes;

[0028] (5) Cut the unprinted non-woven fabric and the printed non-woven fabric into 200mm*200mm, and test its air permeability with the pressure difference method air permeabi...

Embodiment 2

[0031] (1) Weigh 0.3g of disperse blue, disperse red and disperse yellow, add 8g of self-crosslinking adhesive, add water to make up the total mass to 50g, stir at 37°C for 10min at a speed of 700 rpm, and make a disperse dye color pulp;

[0032] (2) Add 1g of printing thickener to the disperse dye color paste, and stir at high speed to make a disperse dye printing paste.

[0033] (3) Spread the polypropylene non-woven fabric on the rubber pad and put the printing screen frame. Pour the adjusted disperse dye printing paste into the printing screen, along the direction of scraping, tilt the rubber scraper, scrape back and forth twice evenly, and then lift the printing screen frame.

[0034] (4) Take out the printed polypropylene non-woven fabric and dry it in an oven at 80°C for 3 minutes;

[0035] (5) Cut the printed non-woven fabric into 50mm*200mm, and test its dry rubbing fastness and wet rubbing fastness in a rubbing fastness meter;

[0036] (4) The test results are sho...

Embodiment 3

[0040] (1) Weigh 0.5g of disperse blue, disperse red and disperse yellow, add 18g of self-crosslinking adhesive, add water to make up the total mass to 100g, stir at 37°C for 10min at a speed of 1000 rpm, and make a disperse dye color pulp;

[0041] (2) Add 1.5 g of printing thickener to the disperse dye color paste, and stir at high speed to make a disperse dye printing paste.

[0042] (3) Spread the polypropylene non-woven fabric on the rubber pad and put the printing screen frame. Pour the adjusted disperse dye printing paste into the printing screen, tilt the rubber scraper along the direction of scraping, scrape back and forth four times evenly, and then lift the printing screen frame.

Abstract

The invention relates to a printing and dyeing method of a polypropylene non-woven fabric material. The method comprises the following steps: dispersing dye in water; adding a self-cross-linking adhesive, and emulsifying to obtain dispersed dye color paste containing the adhesive; adding a thickener to obtain dispersed dye printing gum; printing and drying a polypropylene non-woven fabric, wherein the dye accounts for 0.25-1 mass percent of the dispersed dye color paste, the self-cross-linking adhesive accounts for 15-20 mass percent of the dispersed dye color paste, the thickener accounts for 1-2 mass percent of the dispersed dye color paste, and the balance is water. The method is simple, and low in cost. The treated non-woven fabric does not need to be washed by water, and is great in application prospect.

Description

technical field [0001] The invention belongs to the field of printing and dyeing methods for nonwoven fabrics, in particular to a printing and dyeing method for polypropylene nonwoven fabric materials. Background technique [0002] Polypropylene has developed rapidly since its inception, and has now become one of the four major synthetic fiber varieties. In recent years, fiber-grade polypropylene has gradually been recognized and paid attention to by people as a clothing material with incomparable and excellent properties of some other fibers. Great potential. [0003] Polypropylene fiber itself lacks polar and functional groups, and it is difficult to dye. Neither dope dyeing nor polypropylene modified dyeing is suitable for the application of polypropylene in the clothing industry. Therefore, research and development of dyes and dyeing methods suitable for polypropylene fiber dyeing have become an important subject. [0004] Pigment printing is a printing process that ad...
